The core member defines a second aperture, and the plasma enhancement apparatus is arranged and configured in such a manner that the evaporated cathode source material passes from the cathode source and through the second aperture toward the substrate to be coated by the evaporated cathode source material. The plasma is favorably conditioned as it passes through the plasma enhancement apparatus.

Title: Catalyst for mild hydrocracking of cracked feedstocks and method for its preparation
Inventor: PRADA RICARDO
IPC: B01J29/70
Filed: 1992-05-04
Granted: 2002-12-31
Abstract: A catalyst suitable for mild-hydrocracking of cracked petroleum hydrocarbon feedstocks and selective to diesel fuels contains a catalytically active metal phase constituted by a Group VI-B element, a Group VIII first transition series element and a Group VIII second transition series element, all supported on a titania-alumina support containing about 5% to about 30% by weight titania in the support. The support is prepared by combining titanium oxide and aluminum oxide hydrogels, in appropriate proportions, followed by extrusion, drying, and calcination. The catalytically active metal phase is introduced onto the support by impregnation followed by drying and calcination. The catalytically active metal phase is then sulfided. The produced catalyst is suitable for hydrodesulfurization, hydrodenitrogenation, mild-hydrocracking and aromatics hydrogenation of previously cracked petroleum hydrocarbon feedstocks.

Abstract: A double wall plastic pipe is produced from an extruder with a nozzle having a first orifice and a second orifice downstream of the first orifice feeding into a moving mold tunnel having a first region with a corrugated mold surface and a second region with a belled mold surface. The second region also has openings through the mold wall. A first parison of molten thermoplastic material is extruded from the first orifice into the mold tunnel with the first parison being forced against the corrugated mold surface to shape alternating crests and troughs and against the belled mold surface to shape a bell in the first parison in forming respectively corrugated and cuffed pipe parts. The first parison is ruptured through the mold wall openings to produce an air escape in the bell of the first portion. A second parison of molten thermoplastic material is extruded from the second orifice into the mold tunnel and the second parison is forced to lie against and form a solid laminate with the troughs and the bell in the first parison. Air between the second parison and the bell of the first parison is expelled out of the pipe through the air escape passage in the first parison of the mold tunnel through the mold wall openings in the belled mold surface.

IPC: A61B17/072
Filed: 1992-08-04
Granted: 2004-02-10
Abstract: A surgical fastener applying apparatus is provided with a shipping interlock to prevent premature actuation of the apparatus by the jostling and vibrations which normally occur during shipment of the apparatus from the supplier to the user.   The shipping interlock includes a projection extending from the cam bar retainer and initially disposed through an elongated aperture in an interlock plate having an open distal end, The aperture has a narrow neck portion through which the projection can pass only with sufficient force applied to the cam bar retainer. The shipping interlock is adapted to permit passage of the projecting member when the force exceeds the normally expected forces from jostling of cargo to insure that actuation of the apparatus is intentional.

Granted: 2002-11-19
Abstract: An SSR reply decoding system for separating pulse codes of a series of closely-spaced or overlapping SSR replies is dis-closed. A delay line (11) is connected to receive pulses representing the leading edge of each SSR reply code pulse. The delay line (11) has a length corresponding to at least two bracket lengths of an SSR  reply. A bracket decoder (12) is connected to respective taps (F1, F2) of the delay line (11) for determining the beginning and end of a first SSR reply. A phantom reply detector (11) is connected to the remaining taps for inhibiting the bracket decoder when two replies are represented by pulses in the delay lines, one of the replies having a pulse space from the pulse of another reply equal to a framing pulse period for an SSR reply. The phantom reply detector (13) therefore inhibits the detection of phantom replies. As a discriminate for determining when pulses having the spacing of a framing period belong to different replies, azimuth data is provided which will permit discrimination of these phantom conditions.

Abstract: Geometric objects including points, lines, curves, surfaces and solids are defined and constructed in a system which retains and utilizes relationships and dependencies between objects in a directed graph (digraph) data structure. The primary advantage is automatic updating of the model, preserving dependencies, when an underlying object is changed. Multiple types of parametric curves and surfaces and multiple levels of dependency are easily supported through a recursive program structure. Difficulties of surface-surface intersection and trimming are largely avoided by provision of novel entities which permit construction of accurate and durable joins between surface objects. An example model of a sailing yacht design illustrates six surface objects of several types with the defined dependency relationships. The hull (271) deck (272), cabin forward (273), cabin side (274), cabin aft (275) and cabin top (276) surfaces intersect at joins (278), (279) which are accurate and durable. The connectivity at the joins and the relative positioning of the surfaces are automatically preserved as the model is updated by changing one of the surfaces.

IPC: G10L21/0208
Filed: 1995-08-21
Granted: 1999-06-01
Abstract: A second spectrum parameter of which degree is lower than that of a first spectrum parameter is calculated based on the first spectrum parameter that is output from an encoder. A spectrum postfilter generates a transfer function having a denominator and a numerator wherein said first spectrum parameter is included in said denominator and said second spectrum parameter is included in said numerator, and filters the reduced signal with this transfer function. In addition, it adaptively generates a compensation coefficient based on the first and second parameters. A compensation filter generates a transfer function based the compensation coefficient and filters an output of the spectrum postfilter with this transfer function.

Abstract: The present invention relates to a process for modifying a polyethylene in an extruder. The polyethylene is brought into contact with oxygen or a gas mixture containing oxygen in the extruder, optionally in the presence of a relatively small quantity or preferably in the absence of short-term antioxidant agent. The polyethylene thus brought into contact is treated thermomechanically in the molten state in the extruder supplying a relatively high specific mechanical energy, the treatment being conducted to its term when the value of the loss tangent of the polyethylene characterizing its viscoelastic state decreases with a desired proportion. The polymer thus treated is particularly suitable for being transformed into film by blown extrusion with a considerably increased bubble stability.

Abstract: An intrusion detection system comprises a plurality of sensors and a corresponding plurality of receivers, each receiver coupled to receive via the associated sensor radio frequency signals having a multiplicity of transmissions at different frequencies within a predetermined frequency spectrum. The receiver detects the radio frequency signals and computes for each of a plurality of successive time intervals and for each of the transmission frequencies measurement of signal amplitude over the time interval; compares such signal amplitude measurement with at least one threshold and, if the amplitude exceeds the threshold for a predetermined time period, generates a potential alarm conidtion. A common processor monitors the potential alarm conditions for the plurality of receivers and provides an actual alarm signal when at least one of the receivers indicates potential alarm conditions for a predetermined number of the different transmission frequencies within the same time period. Preferably, the processor compares potential alarm signals from a plurality of sensors and determines that an intrusion has occurred if the potential alarm signal for a particular station does not coincide with a potential alarm signal for a neighbouring sensor. Each receiver may compare potential alarm signals for a plurality of the transmission frequencies and output an intruder alarm signal when potential alarm signals occur simultaneously for more than a preset number of the multiplicity of transmission frequencies.
